-
FIG. 1 shows a cutting system in accordance with an embodiment. The cutting system includes ahydraulic controlling module 10, aPLC controlling module 20, acylinder 40, adam 50, and at least oneresilient member 60. -
FIG. 2 shows thehydraulic controlling module 10 including a valve 11, agasholder 12, afilter 13, apressure sensor 14 connected to thefilter 13, apressure switch 15, a proportional valve YV1, abarometer 16, a solenoid valve module YV, a pressure increasing module 17, ahydraulic pressure gauge 18, and a reversing valve YV4. - The valve 11 can condense gas in the
gasholder 12 to increase an output pressure of thegasholder 12. Thegasholder 12 is connected to an air output pipe (not shown). Thefilter 13, thepressure sensor 14, thepressure switch 15, the proportional valve YV1, thebarometer 16, and the solenoid valve module YV are connected to the air output pipe in sequence. Thefilter 13 catches impurities from the gas of thegasholder 12 and output a first gas with a first pressure. Thepressure sensor 14 detects the first pressure. When the first pressure is smaller than a preset pressure, thepressure switch 15 is closed to prevent the first gas from flowing to the proportional valve YV1. In this position, the hydraulic controllingmodule 10 is not operating. - When the first pressure is greater than the preset pressure, the
pressure switch 15 is open to allow the first gas to flow to the proportional valve YV1. The proportional valve YV1 regulates the first gas to a second gas with a second pressure and then outputs the second gas to thebarometer 16 and an input end of the solenoid valve module YV. The second pressure is smaller than or equal to the first pressure. The proportional valve YV1 regulates a ratio of an input/output pressure. The input pressure is the first pressure of the first gas, and the output pressure is the second pressure of the second gas. When the proportional valve YV1 is fully open, the ratio of the input/output pressure is about 1:1. When the proportional valve YV1 is half-open, the ratio of the input/output pressure is about 2:1. Thebarometer 16 detects and displays the second pressure, and then the second gas flows to the input end of the solenoid valve module YV. - The solenoid valve module YV includes a first solenoid valve module YV2 and a second solenoid valve module YV3. The pressure increasing module 17 includes a
first cylinder 171, asecond cylinder 172 connected to thefirst cylinder 171, and apiston module 176 slidably mounted in thefirst cylinder 171 and thesecond cylinder 172. A diameter of thefirst cylinder 171 is greater than a diameter of thesecond cylinder 172. Thepiston module 176 includes afirst piston 173, asecond piston 174, and a connectingpole 175. Thefirst piston 173 is slidably mounted in thefirst cylinder 171. Thesecond piston 174 is slidably mounted in thesecond cylinder 172. The connectingpole 175 connects thefirst piston 173 to thesecond piston 174. Thefirst cylinder 171 includes a first air chamber 178 and asecond air chamber 179. The first air chamber 178 is located above thefirst piston 173. Thesecond air chamber 179 is located below thefirst piston 173. - The solenoid valve module YV is connected to the first air chamber 178 and the
second air chamber 179. The first solenoid valve module YV2 and the second solenoid valve module YV3 are slidable to block air or allow air to flow. Thus, the first solenoid valve module YV2 and the second solenoid valve module YV3 can increase or decrease pressure in the first air chamber 178 and thesecond air chamber 179, so as to regulate the pressure of the first air chamber 178 and thesecond air chamber 179. Each of the first solenoid valve module YV2 and the second solenoid valve module YV3 has a first state, a second state, and a closed state. When the first solenoid valve module YV2 is located in the first state and the second solenoid valve module YV3 is in the closed state, the first solenoid valve module YV2 allows the second gas to flow into the first air chamber 178. In this position, the pressure of the first air chamber 178 is increased to slide thepiston module 176 downwards. When the first solenoid valve module YV2 is located in the second state and the second solenoid valve module YV3 is located in the first state, the second gas flows from the first air chamber 178 to thesecond air chamber 179. In this position, the pressure of thesecond air chamber 179 is increased to slide thepiston module 176 upwards. - The pressure increasing module 17 further includes a
fuel tank 177 connected to thesecond piston 172. Thefuel tank 177 pours a high pressure oil into thesecond piston 172. When thepiston module 176 is slid downwards, the high pressure oil flows to the reversing valve YV4. When thepiston module 176 is slid upwards, the high pressure oil flows back to thefuel tank 177. Thehydraulic pressure gauge 18 detects an oil pressure of the high pressure oil from the pressure increasing module 17. The reversing valve YV4 is connected to apipeline head 19. The reversing valve YV4 has a first open position and a second open position. When the reversing valve YV4 is located in the first open position, the reversing valve YV4 allows the high pressure oil to flow to thepipeline head 19. When the reversing valve YV4 is located in the second open position, the high pressure oil flows back to the pressure increasing module 17. -
FIG. 3 shows the PLC controlling module including aPLC chip 21, anadapter 22, atouch screen 23 connected to theadapter 22, an analog to digital (A/D)converter 24, and abuzzer 25. ThePLC chip 21 is connected to a 220 V alternating current voltage. The 220 V alternating current voltage supplies power for thePLC chip 21 and theadapter 22 through a switch K. Theadapter 22 converts an alternating current voltage to a direct current voltage, such as 24 V, to thetouch screen 23. ThePLC chip 21 includes a first pin Y0, a second pin Y1, a third pin Y2, a fourth pin Y3, a fifth pin Y5, and a sixth pin Y16. The first pin Y0 is connected to a proportional valve coil L1. The second pin Y1 is connected to a first solenoid valve coil L2. The third pin Y2 is connected to a second solenoid valve coil L3. The fourth pin Y3 is connected to a reversing valve coil L4. A first end of thebuzzer 25 is connected to the fifth pin Y5. A second end of thebuzzer 25 is connected to ground. An input end of the A/D converter 24 is connected to thepressure sensor 14. An output end of the A/D converter 24 is connected to the sixth pin Y16. Thepressure sensor 14 detects the first pressure of the first gas from thefilter 13 and outputs an analog signal to the A/D converter 24. The A/D converter 24 converts the analog signal to a digital signal to thePLC chip 21. ThePLC chip 21 obtains the first pressure by the digital signal and compares the fist pressure with the preset pressure. When the first pressure is smaller than the preset pressure, thePLC chip 21 outputs a high level signal to alarm thebuzzer 25 to remind a user that the first pressure is too low to operate. When the first pressure is greater than or equal to the preset pressure, thePLC chip 21 outputs a low level signal and keeps operating. The user can input a value of the second pressure to thetouch screen 23. Thetouch screen 23 outputs the value to thePLC chip 21. ThePLC ship 21 outputs a controlling signal to the proportional valve coil L1. The controlling signal regulates a current magnitude and a current direction to control the proportional valve YV1. Thus, the proportional valve YV1 outputs the second gas with the value set by the user. ThePLC chip 21 can also output another controlling signal to control the first solenoid valve coil L2, the second solenoid valve coil L3, and the reversing valve coil L4, to control the first solenoid valve module YV2, the second solenoid valve module YV3, and the reversing valve YV4. -
FIG. 4 shows thecylinder 40 includes acylinder body 42, apiston 44, and apipe head 46. Thepiston 44 is slidably mounted in thecylinder body 42. Thepipe head 46 is mounted below thecylinder body 42. Thepipe head 46 is connected to thepipeline head 19 through an oil pipe. Thedam 50 includes amain body 52 and a cuttingportion 54 extending upwards from a top surface of themain body 52. The top surface of themain body 52 defines a pair ofslots 521 for engaging theresilient member 60. In one embodiment, theresilient member 60 is a coiled spring. In assembly, thedam 50 is secured to thepiston 44. Theresilient member 60 is mounted in theslot 521. The cuttingportion 54 can abut a gate mark of a mold. Theresilient member 60 abuts the mold and is elastically deformable to push thedam 50 and thepiston 44. - In use, when the gate mark is cut, the proportional valve YV1 output the second gas to the solenoid valve YV. The
PLC controlling module 20 output a first controlling signal to control the first solenoid valve YV2 in the first open state and the second solenoid valve YV3 in the closed state. The first solenoid valve YV2 allows the second gas to flow into the first air chamber 178. The pressure of the first air chamber 178 increases to slide thepiston 176 downwards and push the high pressure oil to the reversing valve YV4. ThePLC chip 21 controls the reversing valve YV4 in the first open position. In this position, the high pressure oil flows into thecylinder 40 through the reversing valve YV4. Thepiston 44 is pushed by the high pressure oil, and then thepiston 44 pushes thedam 50 to cut the gate mark, and theresilient member 60 is elastically deformed. - After the gate mark is cut, the
PLC chip 21 controls the reversing valve YV4 in the second open position, the high pressure oil flows back to the pressure increasing module 17. At the same time, thePLC chip 21 controls the first solenoid valve YV2 in the second open state and the second solenoid valve YV3 in the first open state. The second gas flows from the first air chamber 178 to thesecond air chamber 179. Thepiston module 176 is slid upwards to push the high pressure oil to flow back to thefuel tank 177, and then theresilient member 60 rebounds to push thedam 50 and thepiston 44 to the initial position. - It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
